Not saving more than 181 rules? [#1974966]

Hello

I am creating a page to let users preview a theme selecting it from a list. I plan to create a rule for each theme based on querystring.param to preview the proper theme according to the param sent by the user.

I tested with a few themes and it works just fine. But I have 200 themes, and after creating 181 rules (result from select count() from themekey_properties), when I try to create the rule number 182 the result page doesn't show any success message nor a failure message, it doesn't show either any kind of error in apache log, and it just the new rule is not created.

If I delete one of the existing rules then I can create that new rule successfully, so I figure it must be a size limit somewhere, but I cannot find the place that limit is set in code. Could you give me a hint?

Thank you in advance.

Best regards.

Strange. AFAIK there's no limit in the code.

What happens exactly when you click save?
Do you see an error page or a white screen or the rule chain as normal?
Anything in the watchdog?

Hello

Thanks for your reply.

No, there is no white screen, just the rule page as expected but without the "green" success message. There are no errors in apache log, about the watchdog, how do I check it?

Best regards.

Watchdog is the internal drupal logger. In a standard installation you'll find it at /admin/reports/dblog

Hello

Nothing in watchdog. I also emptied watchdog log and raised "error" again but nothing was writen.

I don't know if this would help. I deleted a few rules and then created new ones in their places without problems. All new rules created with weight -50 but last one, which was created as weight=51. After that rule, the misfunction started again, as it was number 181 rule. Updating manually weight to a different value (-49) didn't help either.

But I have found an error in apache log which didn't notice earlier on (sorry about that).

[Mon Apr 22 18:34:26 2013] [error] [client XX.XX.XX.XX] File does not exist: /www/sites, referer: http://website.com/subfolder/es/admin/config/user-interface/themekey/properties

My drupal install is on /www/subfolder/ where /www is documentroot, so the web root is on http://website.com/subfolder/. Have I found a bug that takes place when the site is not directly on document root? But, why doesn't it show creating the first 181 rules?.

I created a symbolic link to trick themekey but it didn't work as expected:

[Mon Apr 22 18:36:51 2013] [error] [client XX.XX.XX.X] Symbolic link not allowed or link target not accessible: /www/sites, referer: http://website.com/subfolder/es/admin/config/user-interface/themekey/properties

Does it make any more sense now? I don't even know if this path error has anything to do with it at all. Might it be an attempt to write to a temporary disk file to save memory when there are many rules? If so, I can't find where it is that code.

Best regards.

The javascript based weight feature seems to be a suspect. But that's a core feature :-(
I'll have a look ...

Are you able to test this patch if it solves your issue.

Hello

Thanks for the patch, but it seems it makes no difference.

I applied the patch ("patch -b < 1974966.patch" being at themekey module folder), reloaded rules page (ctrl+F5) and tried to create a new rule. Same behaviour.

I have changed the document root in apache to host the site on / and I don't get the error message about "/sites" but the behaviour still hasn't changed. I cannot create more than 181 rules.

Any other idea? Do you want a dump of themekey_properties table to give it a try?

Best regards.

You need to clear all drupal caches!

All caching is disabled and I have run "empty all caches" at /admin/config/development/performance but it doesn't make any difference (I also logged out and logged back in, just in case).
